Multifunctional chassis

Abstract

The invention discloses a multifunctional chassis. A traveling system and a control part are arranged on a chassis body. In the travelling system, a central differential assembly is connected with a central differential lock switch and a front-rear wheel set independent drive switch by virtue of a circuit; the two ends of a drive axle differential assembly respectively drive tyres to travel through a bevel gear set and a transmission chain; the bevel gear set is arranged in a first supporting sleeve on a half shaft sleeve of the differential axle differential assembly; the transmission chain is mounted in a supporting chain wheel box; front and rear direction control rods are connected with a steering mechanism mounted on the drive axle differential assembly by virtue of a gear pump assembly; and by virtue of a four-wheel steering synchronous opening and closing switch, front and rear steering mechanisms are connected together. The multifunctional chassis is simple in structure, can realize quick and free switching between synchronous driving and independent driving of front and rear wheels of a vehicle, can realize multi-angle free turning and travelling in case of not changing the integral direction of the chassis, and can realize four-wheel complete synchronous steering, thereby reducing damages to a road surface and the vehicle.

Description

technical field [0001] The invention relates to a chassis, in particular to a multifunctional chassis, which belongs to the technical field of vehicles. Background technique [0002] When the vehicle is running, it will encounter various road conditions. At this time, it is necessary to be able to quickly and freely switch between the synchronous drive of the front and rear wheels and the independent drive of the front and rear wheels. The existing chassis that can realize the above functions are complex and expensive to manufacture; When the vehicle changes direction, the vehicle as a whole will change direction accordingly with the change of the wheel direction, which will bring a lot of trouble to the vehicle when turning at a large angle and cause great damage to the road surface, especially in some large vehicles. In special vehicles, when the frame needs to travel horizontally and vertically, the inability to move freely limits the function of the vehicle. In addition...

Problems solved by technology

[0002] When the vehicle is running, it will encounter various road conditions. At this time, it is necessary to be able to quickly and freely switch between the synchronous drive of the front and rear wheels and the independent drive of the front and rear wheels. The existing chassis that can realize the above functions are complex and expensive to manufacture; When the vehicle changes direction, the vehicle as a whole will change direction accordingly with the change of the wheel direction, which will bring a lot of trouble to the vehicle when turning at a large angle and cause great damage to the road surface, especially in some large vehicles. In special vehicles, when the frame needs to travel horizontally and vertically, the inability to move freely restricts the function of the vehicle

In addition, during the steering process of the vehicle, when the power assistance encountered by the two sides of the steering is different, the resulting direction change speed is also different, and a long time will also cause damage to the machine.
